Hello,
The attached file is an example of how tangle wraps the Fortran module in
program main
end program main
which prevents the code from compiling.
There are more instructions on how to reproduce the bug in the attached
bug.org file.

Run with
/usr/bin/emacs -Q -l init.el bug.org
One should be able to click on the following link
- elisp:org-babel-tangle
to tangle (export) the code blocks in this org file.
Then one should be able to execute the code block
- [[code_block_to_execute]]
by using C-c C-c in code block.
However, it does not work because the tangle stage wraps the fortran
module in
program main
end program main
which prevents the code from compiling.
